Magellanic penguin on Argentina's coast Skeleton of a Magellanic penguin. Magellanic penguins are medium-sized penguins which grow to be 61–76 cm (24–30 in) tall and weigh between 2.7 and 6.5 kg (6.0 and 14.3 lb). [3] The males are larger than the females, and the weight of both drops while the parents raise their young.

The extinct penguin Palaeospheniscus wimani is a member of the genus Palaeospheniscus, which belonged to the prehistoric subfamily Palaeospheniscinae. It was the largest member of its genus, being just as large as the Magellanic penguin of today (to which it is quite unrelated).
Humboldt penguins nest on islands and rocky coasts, burrowing holes in guano and sometimes using scrapes or caves. In South America the Humboldt penguin is found only along the Pacific coast, and the range of the Humboldt penguin overlaps that of the Magellanic penguin on the central Chilean coast. It is vagrant in Ecuador and Colombia. [6]
Banded penguins belong to the genus Spheniscus, which was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the African penguin (Spheniscus demersus) as the type species. [ 5 ] [ 6 ] The genus name Spheniscus is derived from the Ancient Greek word σφήν ( sphẽn ) meaning "wedge" and is a reference to the animal's ...
Later, a 2009 study revealed the presence of a species of Plasmodium in Galápagos penguins, a genus of blood parasite that causes Avian malaria. [25] The presence of this parasite suggests that diseases are able to travel from other populations to the isolated Galápagos penguin communities and is likely a cause for population decline.
Paraptenodytes is an extinct genus of penguins which contains two or three species sized between a Magellanic penguin and an emperor penguin (Aptenodytes forsteri). [citation needed] They are known from fossil bones ranging from a partial skeleton and some additional material in the case of P. antarcticus, the type specimen for the genus, and a single humerus in the case of P. brodkorbi.
